Item Description
A
Number of
startups
Shows the content of the cumulative counter of times the inverter is
started up (i.e., the number of run commands issued).
1.000 indicates 1000 times. When any number from 0.001 to 9.999 is
displayed, the counter increases by 0.001 per startup, and when any
number from 10.00 to 65.53 is counted, the counter increases by 0.01
every 10 startups. When the counted number exceeds 65535, the
counter will be reset to 0 and the count will start again.
A
Input watt-hour Shows the input watt-hour of the inverter.
Unit: 100 kWh (Display range: 0.001 to 9999)
Depending on the value of integrated input watt-hour, the decimal point
on the LED monitor shifts to show it within the LED monitor’s resolution
(e.g. the resolution varies between 0.001, 0.01, 0.1 or 1). To reset the
integrated input watt-hour and its data, set function code E51 to "0.000."
When the input watt-hour exceeds 1000000 kWh, it returns to "0."
A
Input watt-hour
data
Shows the value expressed by "input watt-hour (kWh) × E51 (whose
data range is 0.000 to 9999)."
Unit: None.
(Display range: 0.001 to 9999. The data cannot exceed 9999. (It will be
fixed at 9999 once the calculated value exceeds 9999.))
Depending on the value of integrated input watt-hour data, the decimal
point on the LED monitor shifts to show it within the LED monitors’
resolution.
To reset the integrated input watt-hour data, set function code E51 to
"0.000."
A
Number of
RS-485
errors
(standard)
Shows the total number of errors that have occurred in standard RS-485
communication (via the RJ-45 connector as standard) since the power
is turned ON.
Once the number of errors exceeds 9999, the count returns to 0.
A
Content of
RS-485
communication
s error
(standard)
Shows the most recent error that has occurred in standard RS-485
communication in decimal format.
For error contents, refer to the RS-485 Communication User’s Manual.
A
Number of
option errors
Shows the total number of optional communications card errors since
the power is turned ON.
Once the number of errors exceeds 9999, the count returns to 0.
A
Inverter's ROM
version
Shows the inverter's ROM version as a 4-digit code.
A
Keypad's ROM
version
Shows the keypad's ROM version as a 4-digit code.
A
Number of
RS-485 errors
(option)
Shows the total number of errors that have occurred in optional RS-485
communication since the power is turned ON.
Once the number of errors exceeds 9999, the count returns to 0.
A
Content of
RS-485
communication
s error (option)
Shows the most recent error that has occurred in optional RS-485
communication in decimal format.
For error contents, refer to the RS-485 Communication User’s Manual.
A
Option's ROM
version
Shows the option's ROM version as a 4-digit code.
A
Cumulative
motor run time
Shows the content of the cumulative power-ON time counter of the
motor.
The display method is the same as for "Cumulative run time" (
A
)
above.
